Wireless Gigabit Alliance
(WIreless GIGabit) A short-range wireless technology from the Wireless Gigabit Alliance (WGA). Using the unlicensed 60 GHz band, WiGig transmits 1080p HD video from a data source to a TV within approximately 30 feet. Supporting a 7 Gbps data rate, WiGig also provides a wireless technology for gaming, backup and other high-speed data transmission requirements.
WiGig offers an order of magnitude more bandwidth than Wi-Fi, but it throttles down to Wi-Fi speeds in noisy environments. At 60 GHz, the five-millimeter wavelength is highly directional, and beamforming is used to continue operation when objects get in the way. However, if the signal has no obstruction, it can upwards of 60 feet.
Founded in 2009, the Wireless Gigabit Alliance announced Version 1.0 of the specification at year-end. For more information, visit www.wirelessgigabitalliance.org. See wireless USB, WirelessHD, WHDI, beamforming and ISM band.
